articles; and the objects of my invention are,

first, to provide a machine adjustably attached to and adapted to swing with a vertical rotary mast; second, to provide a machine adapted to slide upward and downward on the vertical mast and adapted for retention at a desired place or position on the mast, and, third, to afford facilities for loading and unloading the machine in an expeditious and satisfactory manner. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is an elevation of the machine lowcred down on the mast to loading position, the upper part of the mast being broken. Fig. 2 is an end or side elevation of the same. Fig. 3 is a detail end elevation of the inner side of the carrying-frame. Fig. 4: is a detail elevation ofthe rear side of the mast, showing the upper rear flanged roller, the two gripping-dogs, and the lever for freeing the dogs from the horizontal pin extending through the mast.

Similar characters of reference refer to simi lar parts throughout the several Views.

in the drawings the vertical mast is indicated by A and has a lower center or pivot 3 and is capable of rotary motion in the stationary base B. The upper part of the mast is held in the usual manner, guy-ropes and the like being employed to steady the mast. The mast is preferably square, as shown, and supports a frame comprising horizontal and parallel arms F, with lower and forwardlyextending legs 4: on each side of the mast and a distance therefrom. The arms F extend out forwardly from the mast and at right anglesthereto thatis, horizontally. Thebrackets 5 are secured to the arms F and the legs 4 to support and strengthen said arms. The

arms are separated and held apart by the front flat bar 6 and the round bar 7, both of which are rigidly secured to the arms F.

At the curve of the arms F and the legs 4: at the rear side of the mast is a rear bar 8, and at the lower part of the legsslat the front side of the mast is a similar bar 9. The bars 8 and 9 extend to each side of the frame com prising said arms and legs and are secured thereto. The upper rear bar 8 has a corn trally-located flanged roller 10, and the lower said bar 9 has a similar flanged roller 12, also centrally located on its bar 9. The roller '10 is adapted to roll loosely on its bar 8 and against the rear side of the mast, and the roller 12 is adapted to roll loosely on its bar 9 and against the front side of the mast. On the rear bar 8 and at each side of the roller are dogs or catches 13, connected together by a connecting-bar 14 and adapted to swing together loosely on their pivotal bar 8. (lollars 15 are secured to the bar 8 and retain the roller l0 and the dogs 13 in position on the bar 8, as shown. Similar collars l6 aresecured on the bar 9 to retain the roller 12 in side position.

The mast provided with asuitable number of horizontal holes 17 to receive a pin or pins 18, which extends a distance through the sides of the mast. The dogs 13 have suitable recesses or months with overhanging lips 19, which iit on and over the pin 18 and hang thereon, together with the whole of the carry ingframe, which comprises the arms F, with legs a, brackets 5, bars 7, 8, and 9, and other parts, the whole of which is adapted to slide up anti down the mast A.

The collars 15 on the bar 8 have springs 2t) secured thereto, the function of which is to press against the rear of the dogs to press the same to engagement with a pin 18 when the frame is descending. The upper parts of the dogs are rounded or curved, as at 21, in order to easily pass said pin or pins in the upward movement of the frame and that a proper entrance of the dogs to position----that is, to grip the piu may be effected. On theconnectingbar 14 of the dogs is an eccentric lever loosely connected thereto, and a cord 23 attached. to the upper end of said lever, that when the cord 23 is pulled away from the rear of the mast the dogs are released from their grip of the pin 18 in order to lower said frame from an elevated position.

Coil-springs 2 are on and secured to the connecting-bar 14, and the middle part of said springs engage with and press against the rear of the eccentric lever 22 to retain the upper end of the lever in proximity to the mast.

On the front end and upwardly-extending part of the arms F are secured the outer side bearings 24, and on the upper extending part of the brackets 5 are secured similar bearings 25. The square ends of the side bars 26 rest in said bearings 2st and 25 in stationary position, and on the bars 26 are a number of rollers 27 of one diameter and adapted to revolve on said bars. A number of rollers 27,as shown, facilitate the loading and the unloading of the several pieces of timber, as shown. The rollers on which one said piece rests revolve, while the remaining rollers are stationary. The timber lengths 28 are shown in Figs. 1, 2, and 3 of the drawings.

29 is a hanging fender hooked over the top of the front bar 6 of the arms F and suspended therefrom. The bar 29 is held in position by the brace-rod 30, the lower end of which is hooked into an eyelet 31 on the inner side of the fender, and the upper end of said rod 30 is pivotally connected into a similar eyelet on the inner side of the bar 6. The fender is adapted to fit also on the reverse side of the machine-.that is, hooked on the opposite end part of the bar 6, as shown in broken lines in Fig. 1 of the drawings. The brace-rod 30 answers the purpose of staying the fender, no matter which side of the frame the fender may be. The fender guides and protects the rollers 27 of the machine and the frame against possible friction with the lumber pile when in operation.

One side of the lower part of the mast is supplied with double pulleys 32 in a station ary bearing 33, secured to the mast. These pulleys are adapted to allow the drawing end of the rope 39 to freely pass through, and a horizontal hole 34. through the mast allows the rope to pass through the mast. The drawing end of the rope 39 may also avoid the mast and be drawn in an opposite direction, as shown in Fig. 2 of the drawings.

Each end part of the horizontal bar 7, previously referred to, is supplied with eyeletarms 36, on the inner side of and in close proximity to the frame-arms f. The ends of the lifting-chains 37 are attached to the eyeletarms 36. The opposite ends of the chains 37 are attached to the rope-pulley block 38. The rope 39 extends upward and through a similar pulley block on the upper part of the mast. One end of the rope 39 extends downward and passes through between the pulleys 32, thence in either direction referred to, that the same may be drawn by horse or other power to lift the machine when loaded.

I am aware that vertical masts, both stationary and rotary, supplied with all manner of pulley-blocks and the like, with ropes and chains, and guy-ropes connected therewith and extending in various directions from the mast, are not new.

The operation of the machine is as follows: The lumber or timber to be stacked to a considerable height is usually on the rear side of the mast as the machine is shown in Fig. 1 of the drawings. The lumber 28 is taken from a wagon and placed transversely on the rollers 27, as in same Fig. 1. The machineis then hoisted to a desired height by means of the rope 39 at the lower part of the mast, the flanged rollers operating against the rear and front side of the mast. The pin 18 being placed in the desired hole 17 of the mast, the dogs 13 then fall into position and grip said pin. Consequently the machine, together with the lumber, is secured to the desired height. The mast is then rotated one-fourth of a revolution, as shown in Fig. 2 of the drawings,

' and the lumber is then unloaded by pushing the same from off the rollers 27 onto the pile of lumber. This is very easily accomplished on account of the several rollers 27 operating independently of each other, yet all for the same purpose. \Vhen the machineis unloaded, the mast is then brought to leading position. The eccentric part of the lever 22 is then brought to bear against the mast by means of the pull-rope 23. Consequently the dogs 13 are forced rearward and loosen their grip on the pin 18. In the downward movement of the machine the dogs are held from said pin until they pass the same. Then by the loosening of the cord 23 they are allowed to resume their gripping position, being pressed to this position by means of the springs 20 and the spring 2 pressing the lever 22 to normal position. At this time the dogs have gripped the lower pin 18 of the mast, and the machine is then in position for reloading.

It will be noticed that a desired number of holes 17 for a pin 18 may be in the mast that the machine may be secured at various heights to suit various heights of lumber being piled and when being taken down.

To prevent possible accidents, every hole 17 may have a pin 18. This would not deter nor interfere with the ascent of the frame with a load, but would necessitate the pull and tension of the rope 23 to keep the dogs free from the pin 18.
